In the aftermath of a fourth confirmed travel-associated Zika case in Lee County, the heavy emphasis is on prevention.

A spokesperson with the Lee County Mosquito Control District said the agency is practicing standard control procedures because -- as of now -- local transmission of the virus isn't a problem.

If that changes, the county would drastically change its treatment methods to include aerial measures if a large area is at risk or door to door if the concern is across a smaller area.

"I think it is becoming more serious of a problem, especially along the water beds," said Vicki Pitbladdo of Fort Myers. "Even though you do not travel, somebody who does you are in contact so closely. You don't know who travels and who doesn't."

Calls have been flooding the district, asking if it's safe to go outside or for others to travel to Florida. Experts say yes on both, but encourage protection through the use of bug spray and eliminating any standing water around your residence.

Congressman Curt Clawson visited the Centers for Disease Control on Tuesday to check on efforts being made.

"I am not afraid of it at this point, and it appears that the local people are really on it and doing a lot about it," said David Stanley of Fort Myers. "I think it would be taken care of."
